when rounding a number to the nearest thousand we have to first check the digit in the hundreds place.
if the digit in the hundreds place is equal to or greater than 5 then we increase the value of the thousands place by 1
If the digit in the hundreds place is lesser than 5 then there's no change to the digit in the thousands place
number given is 18 366
digit in the thousands place is 8
digit in the hundreds place is 3. This is lesser than 5 therefore no change is done to the digit in the thousands place. So no change is done to 8.
therefore 18 366 rounded off to the nearest thousand is
18,000
To find the answer simply multiply the numbers together
4*5*3=60
Answer:
pi/6, 5pi/6, 7pi/6, 11pi/6
Step-by-step explanation:
3(sec x)^2 -4=0
Add 4 on both sides:
3(sec x)^2=4
Divide 3 on both sides:
(sec x)^2=4/3
Take square root of both sides:
sec x=plus/minus sqrt(4/3)
Reciprocal identity:
cos x=plus/minus sqrt(3/4)
Simplify the radical:
cos x=plus/minus sqrt(3)/2
So we are looking on the unit circle where the first coordinate of the order pair is either sqrt(3)/2 or -sqrt(3)/2.
This happens at pi/6, 5pi/6, 7pi/6, 11pi/6
Since each month profit is $1,900, it should be multiplied by 1900 as the time goes by. For example, one month profit is 1900, two month profits are 2*1900, three months profits are 3*1900, and so on...
So, it's Y (the amount of profits after X months) = 1900*X
